ABSTRACT
A 52-year-old woman was referred to our hospital because an abnormal shadow appeared in a chest computed tomography to follow up on her type B aortic dissection. The CT showed a slow-growing solitary mass lesion in the left lower lobe. We considered the lesion to be lung cancer, but a CT-guided biopsy and a transbronchial biopsy failed to make a diagnosis. Therefore we performed a left-lower lobectomy. The pathological findings of the resected specimen were a bronchocentric necrotizing granulomatous inflammation. Also, Mycobacterium avium was isolated from the specimen, and other microorganisms were not detected. The patient had neither symptoms of bronchial asthma nor eosinophilia. We reported here a rare case of bronchocentric necrotizing granulomatous inflammation caused by M. avium infection with a solitary mass lesion.
